Hacking an annoying flashlight into something useful (PWJ255)
I bought a couple of Aliexpress T6 flashlights and they are very good for their price, but... they come with some annoying features like blinking and morse SOS. I don't need all that. So I decided to change the circuit. It's quite easy! Some additional information: This chip does not have an undervoltage protection nor does it provide a current limiter for the LED. It's just an electronic on/off switch with some (unnecessary) features. Brightness control is done by 50% or 25% PWM @ 250 Hz but always at full current which is only limited by the resistors. CAUTION - Not all flashlights have an identical PCB! Make sure you solder the bridge at the right place or you will short out the battery or damage other components. Look and think before you modify anything...
